# How do you find the MAXIMUM mass of precipitate? :/ Watch

1. How do you find maximum mass of precipitate?

What i did so far was that I worked out the moles:
100/1000 x 0.500= 0.05 moles
• moles x Mr = Mass

Now when it comes to Mr, is it the Mr of silver nitrate or calcium chloride?
I have tried both ways but my answer didn't match any of the options given?

nope! That's what I thought but it's 7.17 g ?!

Moles=Mass/Mr

AgCl is the ppt, think of the silver nitrate test for chloride ions, white ppt is produced.

So 100/1000 x 0.05

ANS^ x (107.9+35.5) = 7.17g
